Abstract: Compounds of the formula <FORM:1027568/C2/1> wherein R represents H or methyl, R1 represents a hydrocarbon radical of 3 to 10 carbon atoms free from ethylenic unsaturation and having at least two carbon atoms directly attached to that carbon atom of the radical which is bonded to the oxygen atom, and n is 1, 2 or 3, are prepared by reacting together an amine and ether having the formulae <FORM:1027568/C2/2> in substantially equimolar proportions, e.g. by heating at 95-100 DEG C. In the above formulae, R1 may be phenyl, alkylphenyl, isopropyl or t-butyl. The products are used as stabilizers for nitrile polymers (see Division C3).ALSO:Polymers containing at least 10% by weight of a combined ethylenically unsaturated nitrile are stabilized against discoloration by having incorporated therein a stabilizer of the formula (R-CHOH-CH2)2N-CH2-CHOH-(CH2)n-O -R1 wherein R represents hydrogen or methyl, R1 represents a hydrocarbon radical of 3-10 carbon atoms free from ethylenic unsaturation and having at least two carbon atoms directly attached to that carbon atom of the radical which is bonded to the oxygen atom, and n is 1, 2 or 3. In the above formula, R1 may be, for example, a phenyl, alkylphenyl, isopropyl or t-butyl radical. The polymers may additionally contain an alkylphenol (including bisphenols and thiobisphenols). The polymers may be homopolymers, copolymers of two or more nitriles, or copolymers of a nitrile with one or more copolymerizable compounds. Nitriles specified are acrylonitrile, methacrylonitrile, ethacrylonitrile, propacrylonitrile and butacrylonitrile copolymerizable compounds mentioned are monovinyl aromatic hydrocarbons, e.g. styrene, alkyl styrenes and vinyl naphthalene alkyl acrylates and methacrylates acrylamide, methacrylamide and their N-alkyl derivatives and dialkyl maleates and fumarates. The stabilizer, and alkyl phenol if used, may be incorporated by blending with the preformed polymer or adding the stabilizer to the monomer charge from which the polymer is formed. In a modification of this latter embodiment, instead of the stabilizer itself, precursors therefor having the formulae (R-CHOH-CH2)2NH and <FORM:1027568/C3/1> wherein R, R1 and n have the meanings stated above, are added to the monomer charge, which is then heated to effect polymerization, the stabilizer thereby being formed in situ. Plasticizers, lubricants, colorants and rubbery polymers may be added to the stabilized compositions. In examples, acrylonitrile and styrene are copolymerized, in bulk or aqueous suspension, using di-t-butyl peroxide catalyst and in the presence of 1 - phenoxy - 3 - diisopropanolaminopropan-2-ol with or without 2,6-di-t-butyl-p-cresol.

Filed: 1968-11-07
Abstract: A light deflector comprises a switchable electro-optic half-wave plate 6, Fig. 2, selectively operable to change the plane of polarization of a linearly polarized light beam 1 by 90 degrees, and a deflecting element 40 constructed of a plurality of transparent layers, adjacent layers having different refractive indices, and positioned so that the light beam is incident at Brewster's angle and is thus transmitted through or reflected from the deflecting element depending on its plane of polarization. The reflected light beam is aligned with the original direction of the light beam by means of reflecting element 50. In the arrangement as shown in Fig. 2 including multi-layer deflecting elements 40-46, and reflecting elements 50, 56, by selectively energizing electro-optic half-wave crystals 6, 26 and 36 the light beam may be brought to any one of the positions 1f-1n.

Patent ES-364824-A1 (ES)
Title: Apparatus for placing tube stock mounted valves on aerosol containers
IPC: B65B7/28
Filed: 1969-03-14
Abstract: An apparatus for placing valve assemblies on to aerosol containers 2, comprises a container support platform 1, a tapered guide funnel, the smaller end of which is resiliently deformable and a tube stock inserting device including a tubular body 10, an elongate body 13 movable therein, the end of the body 13 facing the platform 1 providing a seat for the valve assembly, which seat communicates with a source of vacuum. The apparatus rotates about a vertical axis whereby it is taken to a series of work stations and at the first a fixed cam engages an arm 9 to lower the device so that it can pick up a valve assembly from a guide (42), Fig. 2 (not shown). At the next station the arm 9 is clear of the cam and the device 4 is raised. At the third station a cam 44 actuates a valve 27 to supply compressed air via a tube 29 to a cavity 20. Compressed air is also supplied to a cavity 18 via a tube 26 but the upper surface of the piston 12 is of greater area than that of the lower surface. The air passes through apertures in a piston 17 to act on the piston 12 thereby driving the body 10 downwardly. The body 10 is so dimen. sioned that the end of the tube 16 lies within the limits of the funnel and as it descends the body actuates a valve 30 whereby compressed air is supplied to a chamber 23 to drive the body 13 downwardly. The lower end 14 of the body pushes the valve assembly through the funnel, the plates 6 of which pivot against the action of springs 7 and then close back over the valve. Movement to the next station brings the cam 44 clear of the valve 27, venting tubes 29, 31 to the atmosphere and causing the pistons 12, 17 to move upwardly by the action of the pressure in the cavity 18, the chamber 23 being vented through the valve 27. The plates 6 retain the valve assembly on the container 1. When the body 10 clears the valve 30, the chamber 23 is vented to the atmosphere therethrough. In an alternative embodiment the tubular body and the elongate body are moved individually by fluid pressure-operated cylinders (52), (56), Fig. 9 (not shown), and there is no equivalent of the hollow cylinder 8.
Patent ES-368891-A1 (ES)
Title: Apparatus for detecting scale formation
IPC: F22B37/56
Filed: 1969-06-27
Abstract: Scale-formation on the heat-transfer surface of a heater wherein a scale-forming liquid such as sea water is heated by a vapour (e.g. steam) is detected by an apparatus comprising a duct 1 for the circulation, via openings 2 and 3, of sea water withdrawn from the heater, a monitoring-tube 4 disposed co-axially within the duct, means for heating the tube 4 so that its surface-temperature is maintained slightly higher than that of the heat-transfer surface of the heater of the distillation plant, and a device for detecting the formation of solid deposit on the surface of tube 4. In a preferred embodiment, tube 4 is made of the same metal as the heater, and is heated by introducing into it, through connection 11 and tube 10, some of the heating-vapour from the heater outlet. Tube 4 is provided with an internal coating of a substance (e.g. gold plating) which promotes condensation, and the vapour partially condenses therein. The condensate flows through tube 18 into reservoir 16 and the non-condensed vapour flows through tube 15 into annular chamber 14. Loop 18a in tube 18 maintains a constant level of condensate in tube 4. The formation of a solid deposit on tube 4 causes an increase in pressure drop within duct 1, and this is indicated by differential manometer 30 which is connected to the duct at three different levels. In other designs, scale-formation can be detected by variations in heat-flow through the wall of tube 4, the temperature of the wall being measured by thermocouple 32 or a change in the rate of flow of condensate into reservoir 16 may be measured by conductivity probes 36 which are connected to an electrovalve 38 controlling discharge orifice 40. Scale-formation in a plant for the desalination of sea water by flash distillation may be detected by the apparatus described. In the case of desalination by means of a multipleeffect evaporator, a detector apparatus could be connected at the outlet of each evaporator.

Title: Feeding and inserting apparatus
IPC: H01R43/20
Filed: 1971-01-14
Abstract: Inserting apparatus for inserting terminals in coil bobbins as improved feed means for feeding a strip of terminals. The apparatus comprises a reciprocable inserter which moves towards and away from the bobbin. During movement of the inserter towards the bobbin, feed fingers which are fixed onto the inserter, engage the strip so that it moves with the inserter towards the bobbin. During return movement of the inserter, the strip is engaged by a detent which is affixed to the frame and which prevents rearward movement of the strip. Feeding is thus accomplished by restraining the strip against rearward movement while the inserter moves rearwardly.
